Quad Core In Future Laptops

Aug. 14, 2009 - PRLog -- The Calpella platform is designed for high-end laptops and will open up for mass uasage of quad core CPUs in mobile computers. For now there will be only 3 Core i7 mobile CPUs:

   * Core i7-720QM
     1.60 GHz
     256 kb L2 cache per core
     6 Mb unified L3 cache
     45W TDP
   * Core i7-820QM
     1.73 GHz
     256 kb L2 cache
     8 Mb unified L3 cache
     45W TDP
   * Core i7-920XM
     2.00 GHz
     256 kb L2 cache
     8 Mb unified L3 cache
     55W TDP

All three CPUs come in 989-pin mPGA packaging and with an integrated dual-channel DDR3 memory controller. They all support HyperThreading so 8 processes can be run simultaniously. Because of the memory controller the Clarksfield CPUs will use a little more power than existing Core 2 Quad mobile CPUs, but overall system power usage is expected to be about the same.
